Unlike the bacterial community, Symbiodiniaceae composition was only distinct between host species at high thermal variability sites, suggesting that different factors shape bacterial versus algal communities within the coral holobiont. Our findings shed light on how domain-specific shifts in dynamic microbiomes may allow for unique methods of enhanced host fitness.Biosurfactants are microbial surface-active compounds with antimicrobial and antioxidant activities that display a range of physiological functions. In this study, a strain isolated from a Cameroonian fermented milk "pendidam" and identified as Lactobacillus casei subsp. casei TM1B was used for biosurfactants production. The biosurfactants produced by L. casei TM1B with molasses as the substrate had a good surface (40.77 mN/m) and emulsifying (84.50%) activities. The scavenging of the ABTS+• radical (IC50 value of 0.60 ± 0.03 mg/mL) by the biosurfactants was found to be higher than that of DPPH• radical (IC50 value of 0.97 ± 0.13 mg/mL). The maximum chelating activity of biosurfactants (82.29%) was observed at 3.5 mg/mL. The biologically active compound of the biosurfactants produced by L. casei TM1B was identified as 2,5-O-methylrhamnofuranosyl-palmitate, a novel rhamnolipid-like biosurfactant by using chemical, Fourier transform infrared spectroscopy, gas chromatography-mass spectrometry, and NMR analysis. The biosurfactants were bactericidal against several Gram-negative and Gram-positive pathogens (minimum inhibitory concentration values ranged from 3.22 to 12.83 mg/mL), and scanning electron microscope analysis revealed bacterial cell walls and membranes as main targets.Objectives This study aimed to investigate physicians' and pharmacists' perceptions of the importance of pharmacists' role in healthcare in Egypt, and actual delivery of these roles in practice. Identifying any differences and inconsistencies between these will inform future strategies that maximize pharmacists' professional contribution to hospital practice. Methods A self-administered questionnaire using a 5-point Likert scale was distributed to a convenience sample of physicians (500) and pharmacists (500) practicing in selected private or public hospitals in Egypt. The main sections of the questionnaire comprised statements that pertained to physicians'/pharmacists' views on the importance of pharmacists' roles and their actual delivery in practice. Key findings In this study, physicians showed low scores for both the importance of and the delivery of advanced patient-facing clinical pharmacy roles such as suggesting prescription medications, and designing treatment plans. In comparison, pharmacists were more positive on both of these aspects of their roles. High mean scores were reported by the physicians for pharmacist's traditional roles such as patient counselling, assessing compliance, preventing medication errors and treating minor illnesses. Both physicians and pharmacists reported poor pharmacists practice as drug information resources despite their high perception of the importance of that role. Conclusion This study suggested that in hospitals in Egypt, there are significant differences between physicians' and pharmacists' perception and practice, and pharmacists' clinical skills are underutilized in health care.A systematic comparison framework for selecting the best retrofitting alternative for a water resource recovery facility (WRRF) is proposed in this work. The procedure is applied comparing different possible plant configurations to retrofit an existent anoxic/oxic (A/O) WRRF (Manresa, Spain) aiming to include enhanced biological phosphorus removal (EBPR). The framework for comparison was built on system analysis using a calibrated IWA ASM2d model. Selleck SEL120-34A A multicriteria set of performance variables, as the operational and capital expenditures (OPEX and CAPEX, respectively) and robustness tests for measuring how fast the plant configuration refuses external disturbances (like ammonium and phosphate peak loads), were used for comparison. Starting from the existent WRRF, four plant configurations were tested single A2 /O (only one anoxic reactor converted to anaerobic), double A2 /O (two anoxic reactors converted to anaerobic), BARDENPHO, and UCT. The double A2 /O plant configuration was the most economical and reliable alternative for improving the existent Manresa WRRF capacity and implementing EBPR, since the effluent quality increased 3.8% compared to the current plant configuration. In addition, the double A2 /O CAPEX was close to €165,000 which was at the same order of the single A2 /O and lower than the BARDENPHO and UCT alternatives. PRACTITIONER POINTS Four configurations including EBPR were evaluated for retrofitting an A/O WRRF. A new multicriteria comparison framework was used to select the best configuration. Up to 13 criteria related to effluent quality, robustness and costs were included. A single function based on the combination of all the criteria was also evaluated.The new coronavirus SARS‐COV‐2 is currently impacting life around the globe 1. The rapid spread of this viral disease might be highly challenging for health care systems. This was seen in Northern Italy and in New York City for example2. Governments reacted with different measures such as shutdown of all schools, universities and up to a general curfew. All of those measures have a huge impact on the economy. The United Nations secretary general has stated recently “The COVID‐19 pandemic is one of the most dangerous challenges this world has faced in our lifetime.Aims and objectives To examine nurses' perceptions of physical and verbal violence perpetrated by patients and visitors and to investigate themes surrounding gender and the incidence of violence. Background The prevalence of violence towards nurses is a concern for nurses and hospital administrators. However, nurses who work in acute care and mental healthcare settings are particularly at high risk. This study examines the occurrence, type of violence and gender issues in a regional public hospital of Queensland Australia. link2 Design An exploratory, qualitative design. Methods Focus group interviews with 23 nurses from Emergency Department (ED), Intensive Care Unit (ICU) and Psychiatry Department (PD) working in Queensland regional public hospital, Australia. Qualitative data were transcribed and thematically analysed manually and by NVivo. COREQ research reporting checklist followed. Results Participants reported frequent incidents of verbal and physical violence on a daily basis. Severe incidence included punching, kicking, biting and scratching, as well as threats of using weapons, such as knives. Patients were more likely to exhibit physical violence, especially towards male nurses, while hospital visitors including patient's family were more likely to exhibit verbal violence. Allocating male nurses in volatile areas and to care for violent patients raises concerns that the male nurses may be seen by their patients as "bodyguards" and not as a professional nurse. Conclusion Findings indicate that staff believe that violence is increasing, feel the burden to accept that violence as part of the job and that the bureaucratic processes of the organisation make it difficult to address violence or get support. Organisations need to be vigilant in ensuring assistance is accessible and simplified. Relevant to clinical practice This study contributes new knowledge to the discussion concerning of gender issues. Identifying gender issues could assist in developing the necessary interventions to reduce workplace violence.Objective Genetic testing for hereditary breast and ovarian cancer (HBOC) due to pathogenic variants in BRCA1 or BRCA2 is why most women present to familial cancer centers. Despite being assessed as low risk for HBOC, many women proceed with genetic testing. This study explored the genetic testing experiences of unaffected women at low risk of HBOC to clarify what motivates these women to have testing, and what are the implications of the results. Methods A qualitative approach was taken. Participants included women who had genetic testing for HBOC from 2016-2018 at the Parkville Familial Cancer Centre in Melbourne, Australia. In-depth, semi-structured interviews were conducted, and thematic analysis was undertaken on transcripts; transcripts were coded, codes were organized into a hierarchical system of categories/subcategories, and key themes were identified. Results Analysis of 19 transcripts identified five themes family underpinned all motivators for HBOC genetic testing; health professionals were influential throughout the process; participants were planning for a positive result; results influenced screening-anxiety and frequency; and negative results gave participants relief in many different ways. The three participants with positive results reported feeling shocked at the results and empowered giving this information to family members. Conclusions Women at low HBOC risk may be motivated to seek genetic testing, and access to this is increasingly offered through non-genetic health professionals. Professionals can support clients through genetic testing by recognizing familial experiences, providing accurate information, addressing risk perceptions, and understanding cancer anxiety felt by many women.

To address this issue, we employ all-atom classical molecular dynamics simulations and investigate the interactions between nucleic acids and g-C3N4. It is revealed that, toxicity is modulated through a subtle balance between electrostatic and van der Waals interactions. When the exposed nucleobases interact through predominantly short-ranged van der Waals and π-π stacking interactions, they get deviated from their native disposition and adsorb on the surface, leading to loss of self-stacking and intra-quartet H-bonding along with partial disruption of the native structure. In contrast, for the interaction with double-stranded structures of both DNA and RNA, long-range electrostatics govern the adsorption phenomena since the constituent nucleobases are relatively concealed and wrapped, thereby resulting in almost complete preservation of the nucleic acid structures. Construction of free energy landscapes for lateral translation of adsorbed nucleic acids suggests decent targeting specificity owing to their restricted movement on g-C3N4. The release times of nucleic acids adsorbed through predominant electrostatics are significantly less than those adsorbed through stacking with the surface. I.Novel coronavirus disease (COVID‐19) may be associated with thrombocytopenia which might have different mechanisms in different patients and in different phases of the disease. link3 Cytokine release, thrombotic consumption or autoimmune destruction are some leading etiologies of thrombocytopenia in COVID‐19. This case report presents a 41‐year‐old male COVID‐19 patient who had petechiae and purpura as the referral symptoms. Laboratory tests revealed isolated thrombocytopenia with no other additional pathologic findings. Most probable diagnosis was COVID‐19 induced immune thrombocytopenia (ITP) and high dose intravenous immunoglobulin (IVIg) treatment generated a good response. There were four other recent publications with a total of eight cases in the literature. The presented case was discussed in comparison with those similar cases.
